Abstract

Abstract : Major growth in the image sensor market is largely as a result of the expansion of digital imaging into cameras, whether stand‐alone or integrated within smart cellular phones or automotive vehicles. Applications in biomedicine, education, environmental monitoring, optical communications, pharmaceutics and machine vision are also driving the development of imaging technologies. Organic photodiodes (OPDs) are now being investigated for existing imaging technologies, as their properties make them interesting candidates for these applications. OPDs offer cheaper processing methods, devices that are light, flexible and compatible with large (or small) areas, and the ability to tune the photophysical and optoelectronic properties − both at a material and device level. Although the concept of OPDs has been around for some time, it is only relatively recently that significant progress has been made, with their performance now reaching the point that they are beginning to rival their inorganic counterparts in a number of performance criteria including the linear dynamic range, detectivity, and color selectivity. This review covers the progress made in the OPD field, describing their development as well as the challenges and opportunities. Abstract : Organic photodetectors (OPDs) are investigated for application in imaging technologies. OPDs can be light and flexible, with the optoelectronic properties tunable at both the material and device level. Their performance parameters such as linear dynamic range, detectivity, and color selectivity are excellent. The progress of OPDs is covered here; their development as well as the challenges and opportunities are described.
